A new culture medium for in vitro rhizogenesis of grapevine (Vitis spp.) genotypes

A modified culture medium is presented that promotes in vitro rooting of grapevine rootstocks and Vitis vinifera L. cultivars even in the absence of plant growth regulators. Study of 15 Vitis genotypes indicated a strong genotype-dependent response to culture medium and growth regulators with respect to formation of roots in one-node shoot segments (...)
